2 weeks

Focused review

Days 1–4: map and lessons. Days 5–10: targeted questions and an error log. Days 11–14: mixed retrieval.

4 weeks

Steady blocks

Week 1: map and lessons. Weeks 2–3: topic blocks and spaced retrieval. Week 4: mixed review.

6 weeks

Build and consolidate

Weeks 1–2: lessons. Weeks 3–4: shelf blocks. Week 5: mixed application. Week 6: weak-area retest.

Retrieve, then resume

After each question, name one wrong-answer discriminator and the finding that would change management. Return after 48 hours and on day 7 to explain the decision without looking. Scale question blocks to available eligible questions; no fixed count is promised.
